DETAILED DESCRIPTION

Some exemplary embodiments of the present application are hereinafter described in detail with reference to the accompanying drawings. Although the accompanying drawings illustrate the exemplary embodiments of the present application, it shall be understood that the present application may be practiced in various manners, and the present application shall not be limited by the embodiments illustrated herein. On the contrary, these embodiments are described herein only for the purpose of better understanding the present application, and may integrally convey the scope of the present application to a person skilled in the art.

Referring to FIG. 1, one embodiment of the present application provides a power supply manageable wearable device 1. A smart device 2 supplies power to the wearable device 1 via a microphone interface 21. The wearable device includes: a power management module 11 connected to the microphone interface 21, a control module 12 and a function module 13 that are connected to the power management module 11 respectively.

Specifically, the smart device 2 receives a voice communication instruction via the microphone interface 21 and meanwhile the smart device 2 supplies power to the wearable device 1 via the microphone interface 21, and the microphone interface 21 is a multiplexed interface.

The control module 12 monitors whether a user instruction includes a voice communication instruction.

If the user instruction includes the voice communication instruction, the power management module 11 is enabled to supply power to a microphone and output a first voltage to supply power to the control module 12.

Otherwise, the power management module 11 is enabled to cut off power supply to the microphone and output a second voltage to supply power to the control module 12 and the function module 13, or output a first voltage to supply power to the control module 12 and output a second voltage to supply power to the function module 13, the first voltage being less than the second voltage.

Specifically, the function module 13 is configured to perform user biological feature detection, for example, heart rate detection, step counting, body temperature detection, blood oxygen detection and the like.

If the control module 12 monitors that the user instruction includes the voice communication instruction, that is, the microphone operates, the power management module 11 supplies power to the microphone, and only needs to provide the lower first voltage to the control module 12 for supplying power, such that normal operation of the microphone is ensured.

If the control module 12 monitors that the user instruction does not include the voice communication instruction, that is, the microphone does not operate, the power management module 11 outputs the second voltage to supply power to the control module 12 and the function module 13, or, outputs the first voltage to supply power to the control module 12 and the second voltage to supply power to the function module 13. The control module 12 constantly detects the user instruction, and the function module 13 performs user biological feature detection, for example, heart rate detection, step counting, body temperature detection, blood oxygen detection and the like.

Likewise, it shall be understood that, to streamline the present application and facilitate understanding of one or more of various aspects of the present application, in the above description of the exemplary embodiments of the present application, various features of the present application are sometimes incorporated in an individual embodiment, drawing or description thereof. However, the method according to the present application shall not be explained to embody the following intension: the present application seeking protection claims more features than those explicitly disclosed in each of the appended claims. To be more exact, as embodied in the appended claims, the inventive aspects lie in that fewer features than all the features embodied in an individual embodiment as described above. Therefore, the claims observing the specific embodiments are herein incorporated into the specific embodiments, and each claim may be deemed as an individual embodiment of the present application.

Those skilled in the art should understand that modules in the devices according to the embodiments may be adaptively modified and these modules may be configured in one or more devices different from the embodiments herein. Modules or units or components in the embodiments may be combined into a single module or unit or component, and additionally these modules, units or components may be practiced in a plurality of sub-modules, subunits or subcomponents. Besides that, such features and/or processes or at least some of the units are mutually exclusive, all the features disclosed in this specification (including the appended claims, abstract and accompanying drawings) and all the processes or units in such disclosed methods or devices may be combined in any way. Unless otherwise stated, each of the features disclosed in this specification (including the appended claims, abstract and accompanying drawings) may be replaced by a provided same, equivalent or similar substitution.

In addition, those skilled in the art shall understand that, although some embodiments described herein include some features included in other embodiments, rather than other features, a combination of the features in different embodiments signifies that the features are within the scope of the present application and different embodiments may be derived. For example, in the claims appended hereinafter, any one of the embodiments seeking protection may be practiced in any combination manner.

Embodiments of the individual components of the present application may be implemented in hardware, or in a software module running one or more processors, or in a combination thereof. It will be appreciated by those skilled in the art that, in practice, some or all of the functions of some or all of the components in the message prompting apparatus according to individual embodiments of the present application may be implemented using a microprocessor or a digital signal processor (DSP). The present application may also be implemented as an apparatus of a device program (e.g., a computer program and a computer program product) for performing a part or all of the method as described herein. Such a program implementing the present application may be stored on a computer readable medium, or may be stored in the form of one or more signals. Such a signal may be obtained by downloading it from an Internet website, or provided on a carrier signal, or provided in any other form.

Reference herein to "one embodiment", "an embodiment" or to "one or more embodiments" implies that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least one embodiment of the present application. Further, it should be noted that instances of the phrase "in one embodiment" herein are not necessarily all referring to the same embodiment.

In the specification provided herein, a plenty of particular details are described. However, it can be appreciated that an embodiment of the present application may also be practiced without these particular details. In some embodiments, well known methods, structures and technologies are not illustrated in detail so as not to obscure the understanding of the specification.

It should be noted that the above embodiments illustrate rather than limit the present application, and those skilled in the art may design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference sign placed between the parentheses shall not be construed as a limitation to a claim. The word "comprise" does not exclude the presence of a module or a step not listed in a claim. The word "a" or "an" used before a module does not exclude the presence of a plurality of such modules. The present application may be implemented by means of a hardware comprising several distinct modules and by means of a suitably programmed computer. In a unit claim enumerating several devices, several of the devices may be embodied by one and the same hardware item. Use of the words "first", "second", "third" and the like does not mean any ordering. Such words may be construed as naming.
